Abstract
A food service process including a hot food dish and an insulated dome. Hot food is served onto the dish, the dome set over the dish, and the dome covered hot food dish is delivered to the intended consumer. A thermochromic member disposed in a heat conductive sleeve is mounted in the lift knob of the dome. Thus, without lifting the dome, the server and/or the consumer can readily determine from the color of the member whether the covered food is still at a safe heating temperature. In an alternative process, the dome is first preheated and then placed over the plate of hot food. Then similarly, after the plated food is transported to a different location and delivered for consumption, the server and/or the consumer can determine from the color of the thermochromic member whether the food is still at a safe temperature for consumption.
